It’s easy to be wary of claims of long-lasting battery life, as so many products out there promise reliable and worry-free battery power and then fail to deliver. So when the Sensative Strips Door/Window Sensor arrived to the market – a sensor thinner than two credit cards stacked together, and featuring a brand-new kind of battery that lasts for 10 years – some of us were skeptical.
Sensative recently turned to Sony to put their product’s power consumption to the test with the help of Otii – a new energy-optimization tool that measures and analyzes the power consumption behaviors of battery-powered devices. Of its many useful features, it allows the user to pinpoint the cause of a draining battery by syncing the software’s debug output with its power readings. Otii’s findings confirmed that the battery in Strips can last much longer than 10 years with optimal configuration and network conditions.
Key Facts:
1. The 3mm thick custom-built battery has a capacity of 480 mAh.
2. A strong coating and reliable build make Strips weatherproof and efficient in changing temperatures.
3. In a small house with a single-hop setup (no range extenders), more than 50% of the battery’s capacity remains after 10 years.
4. In a normal-sized house with a dual-hop setup (one range extender), more than 33% of the battery’s capacity remains after 10 years.
5. Strips is equipped with a battery booster that engages battery voltage in very low temperatures and towards the end of battery life.
Take a look at the infographic below and let us know if you’re still having second thoughts!

Mine lasted 14 months in a zero-hop configuration (communicating directly with the hub). I had the LED turned off, wet/dry reporting turned off, reduced frequency of wake-up, … I did everything in terms of configuration that is recommended to maximize battery life, and the sensor never indicated that it was needing to re-transmit any messages. The battery went from >90% one day to exactly 1% the next day and was then dead within a week. So I got 11.7% of the advertised 10 years.

If the sensor goes from 100% to 10% rapidly it may be a sign of communication issues where the battery is not being reported correctly. We recommend getting in touch with Sensative’s support team so they can help you troubleshoot the problem. This is definitely not normal behavior for these.

One of my Comfort Strips suddenly reported a battery at 10% down from 100% the Day before. The strip has been operative for about 4 Months (!). 10 years compared to 4 Months…

A 10 year battery life is huge!
Set it and forget it. Most people don’t want to think about replacing the batteries in their smart home devices. This should go over pretty well.

real world test: 3 strips, placed in an appartment on doors and windows:
strip 1 (9/2018) just hit 25%. (so 5 years = 75%)
strip 2+3 (03/2020) have been @ 75% for around a year now
Real life expectancy appears to be betweeen 6-8 years, in a good, single hop network setup.
